SUCTION CLEANER.

Application filed June 28,

' fan blades mounted directly upon the outer side thereof, the air passing through the nozzle cooling the motor.

Another object is to mount directly upon the bottom of said casing a rotary brush adapted to be driven in the inlet of the nozzle by said motor.

The foregoing and other objects are obtained by the suction sweeper shown in the accompanying drawing. It is to be understood that the invention is not limited to the specific form thereof shown and described.

Figure 1 of the accompanying drawing is a diametral section through the nozzle of a suction sweeper embodying the invention; and I FigureQjs a sectional plan on line 22 of Figure 1 Referring to the drawings, the numeral represents a cylindrical nozzle open atits bottom to provide a suction inlet and supported in any suitable manner as by wheels indicated at 11, 11, domestic sweepers having an operating handle 12 attached thereto and-the top of member 10 delivering dust-laden air to a suitable collector indicated at 13.

Arranged in nozzle 10 is a vertical fiked shaft 14 on which is journaled a casing 1! having fan blades 16, 16 secured .upon the outer periphery thereof. Shaft 14 has fixed thereon an armature 17 and the inner pcriphery of casing has fixed thereon a field 18 which provides a motor to which electricity may be supplied by cable 19 ex- 'tended downwardly through shaft 1 1 into 1927,. Serial No. 202,036.

motor/casing 15 and connected to the armature of said motor:

On the bottom of motor casing 15 is secured a disc brush 2O rotating in the suction inlet of the nozzle in engagement with the surface being cleaned; It will be under.

stood that any suitable cleaning devices used on the rotary elements of vacuum cleaners may be employed instead of the simple' brush 2t),

In use, the/motor will be continuously driven, thus driving brush 20 in engagement with the surface being cleaned to loosen dirt, ravellings, etc, and also driving fan blades 16 creating a. suction of air upwardly about motor casing 15 into the collector 13, the current. of air effectively cooling the motor.

It will appear from the foregoing that a simple, inexpensive, but very etfective suction cleaner has been provided by the invention and that. modifications of said invention may be resorted to without departing from the spirit thereof or the scope of the appended claims.

What is claimed is:

1. A suction sweeper including a suction nozzle, a self-contained motor mounted in thenozzl-e and including a rotatable casing housing the motor, a suction fan secured to the outside of the motor casing, and a brush on the bottom of the motor casing in the suction inlet.

2. A suction sweeper including a suction nozzle, a motor including a fixed armature and revolving field mounted in said nozzle, a rotatable casing housing the motor and to which the field is attached, a suction fan secured to the outside of the motor casing, and meanson the bottom of the casing adapted to rotate therewith in engagement with the surface cleaned to loosen dirt therefrom.

3. A suction sweeper including a suction nozzle, a motor including a fixed armature and revolving field mounted in said nozzle, a rotatable casing housing the motor and to which the field is attached, and a suction fan secured to the outside of the motor casing.
